Hi,
How are you? It is good that your MRI was fine. One type of
migraine is called hemiplegic
migraine. This presents with pins-and-needles feeling, numbness on one side of the body ( which can include your arm, leg, and/or one side of the face), weakness or paralysis on one side of the body, loss of balance and coordination, dizziness, nausea and vomiting and sensitivity to light, sound, and smell. Have this checked by your doctor for proper evaluation. Take care and do keep us posted.
